| 摘要 |
A transmissive liquid crystal (LC) control structure comprising: a superstrate (44) having a first surface (44a) having a GaN HEMT structure disposed thereon to provide a conductor on the first surface of said superstrate; a substrate (42) having a first surface disposed over and spaced apart from the first surface of said superstrate and having a GaN HEMT structure (43) disposed thereon to provide a conductor on the first surface of said substrate and wherein the GaN HEMT structure on one of the superstrate and substrate surfaces are patterned into individual electrodes; a polymer network liquid crystal (PNLC) (48) disposed in the space between the first surface of said superstrate and the first surface of said substrate; and a control circuit coupled to the individual electrodes. |
